    I'm working on a simple LED thing for a friend. It will simply be a microcontroller blinking around with some RGB LEDs on a stage. There will be maybe 5 stations with 5-10 of the LEDs each all connected to a box that will control them. I'm trying to think of the best way to connect them around a stage so I figure telephone wire and contacts would be the cheapest. I found some that are rated for much higher than a few volts at 1 amp but I'm worried about how to actually connect them to the wire. I don't want to buy a crimper or some special tool.

    It says that it is IDC, does that mean that it is definitely the sort that just clamps down onto the wires? The data sheet does not seems particularly detailed in that area...

    Thanks

    No you still need a tool to press and fully seat the small brass IDC terminals into the wire.
    You can pick up the modular tool for under 10 bucks though..

    IDC= Insulation Displacement Connector
    The way it works is to pierce the insulation and allow the contacts to rest against the conductor.

    Toolless IDC is one that doesn't require a tool to seat the wires..
    Many keystone jacks are toolless IDC now. (which could be used for the female part of your connections)

    You could just buy premade rj11 phone cables (or ethernet RJ45) and just use the keystone jacks to breakout the wires where needed.

    Of course a hammer and small flat screwdriver can be used to seat wires in many IDC connectors too. :)

    Thanks guys, I just grabbed one today. But I still have one more simple question.

    When wiring the connectors, do they cross over so that each plug would match, Conductor 1 on pin 1 of each connector, conductor 2 on both pin 2's... Or are they mirrored, so that conductor 1 is on pin 1 of one connector, and pin 4 of the other?

    Pin 1 is marked, usually with a small triangle. It is marked on both connectors.
